Amorphous Alloy Electrical Steel

Amorphous Alloys Electrical Steel

Brief Introduction

  • The amorphous magnetic material was first compounded by Duwes using liquid flame hardening in 1960. The amorphous material has excellent magnetic properties, corrosion resistance, wear resistance, high strength, hardness and toughness, high resistivity and electromechanical coupling performance. Prepared by rapid solidification of 80% Fe and 20% metalloid elements of Si. B.

  • Fe-based amorphous strips and wildly used as cores of distribution transformer, pulse transformer, magnetic amplifier, saturable reactor, PFC inductor and filter inductor. It also has a wide application prospect on motors, power and distribution transformers.

Technology characteristics

  • High saturation magnetic induction------reduce winding circles and volume of the products.

  • High resistivity, Low coercivity------improve efficiency of the product.

  • Low loss (as 1/3-----1/5 of silicon steel)------reduce temperature rise of products and improve efficiency.

  • Low excitation power------reduce no-load current and noise of the products.

  • Variable permeability------different requests for application achieved by different heat treatment processes of Iron cores.

  • Well electricity frequency------better electromagnetic performance than silicon steel in frequency of 400 10KHZ.

  • Good temperature stability------work at the temperature of -45 C 225 C for a long time.
